SPOOL FOR CONTAINING THREAD.

SPECIFICATION forming part of Letters Patent No. 594,190, dated Novemberas, 1897. Application filed Tune 3, 1896- Serial No. 594,128. (Nomodel.)

To all whom it may concern:

Be it known that I, BENJAMIN LATHAM ARM- STRONG, of New London, in thecounty of New London and State of Connecticut, have invented a new anduseful, Improvement in Spools for Containing Thread, of which thefollowing is a specification.

My invention relates to an improvement in spools for containing threadfor the market, with the object in view of providing a light inexpensivespool and one capable of being placed upon a spindle to rotate freelywhen it is desired to use the thread on a sewingmachine.

The wooden spool in common use is comparatively costly and for purposesof shipment weighs so much that its use greatly increases the cost ofthe thread to the consumer.

The paper quill, While overcoming the bjectionable weight and cost ofthe wooden spool, must be made of awkward length or else shed the threadfrom its ends and at best permits the thread to become spread and liableto snarl.

My present invention contemplates a spool made of paper or othersuitable light cheap material having a central socket for the receptionof a spindle, both for arresting the thread on and unwinding it from thespool, and provided with flaring ends to retain the thread neatly andsecurely in position.

In the accompanying drawings, Figures 1 and 2 represent, respectively,in side and end elevation the completed spool. Fig. 3 represents theblank from which the spool is made. Fig. 4: represents the first step inthe formation of the spool, and Fig. 5 represents the second step in theformation of the spool.

The spool consists of an oblong strip of paper or its equivalent coiledto form a tubular core and folded to form a flattened body portion whichembraces the tubular core and extends in opposite directions from thecore to form suitable retaining ears or Wings.

The oblong strip of paper is denoted by A, and it is first coiled at oneend to form the core a, as shown in Fig. 4. The coiled portion a is thenbodily laid over onto the strip of paper at a distance from where it wascoiled, forminga folded wing or ear a, as shown in Fig. 5. The oppositeend of the strip is then folded over onto itself to form the oppositewing or ear a and over the coiled portion a and secured to thesaidcoiled portion by some suitable glue, the coil being secured to thestrip of paper where it was first laid over.

The folded wings a a may be cut away intermediate of their ends to forma contracted body portion, as shown in Fig. 1.

In speaking of the spool as adapted to contain thread I Wish to beunderstood as including silk, yarn, or any flat cord or tape as might besuitable for spooling purposes.

What I claim is- A spool formed of paper or its equivalent andconsisting of a single strip coiled to form a tubular core and folded toform a flattened body portion embracing the tubular core and extendinginopposite directions from the core to form retaining-ears, substantiallyas set forth.

BENJAMIN LATHAM ARMSTRONG.
